float_multiply

Summary. Multiply two XFLs.

Signature.

int64_t float_multiply(int64_t float1, int64_t float2);

Parameters.

Name	Type	Description
float1	int64_t	First XFL.
float2	int64_t	Second XFL.

Return value. The XFL product; if either operand is 0 the result is 0. Errors: INVALID_FLOAT (-10024) if either argument is invalid; XFL_OVERFLOW (-30) if the product overflows.

Common failure patterns.

• Multiplying two very large values → XFL_OVERFLOW.

Caveats / notes.

• To scale by an integer ratio without first converting the ratio to an XFL, prefer float_mulratio — it takes uint32_t numerator/denominator directly.

Minimal example.

int64_t product = float_multiply(a, b);
